Generally most forms of PGO does not try to capture number of mispredicted branches (which isn't the same as how often a branch is taken).

I once got that question, started with the keyboard switches and the interrupts, and the interviewer sighed and asked me to get to the stuff in the browser.

The demoscene still exists, although it doesn't seem to attain a lot of new members, and most (not all!) of the activity is back on oldschool platforms like Amiga or similar. See e…

No, not really. Highway generates rather bad code as soon as you step outside a pretty narrow vertically-oriented scope, in my experience.

You may be interested in OpenMP.

Interesting, but if you are not robust to corrupted/malicious data, it is really in a different class of algorithm and it is hard to compare speeds directly. From memory, 2505 MB/s…

I was at a talk where he brought up exactly this (I also once did a talk alongside him, but that's a different story). He said there would be two changes: 1. It would have 128-bit …

So, in your example, each request needs 0.1 core-seconds of PoW. Is that right? Or, since you're saying 10000 hashes across the entire machine and 1000 needed, then on a typical 96…

I don't have a book, but my best recommendation would be: Learn how to measure. Whatever language you are using should have a profiler. Learn how to use it and look at how your cod…

This is called “installing a cryptominer on your web page” and is generally considered illegitimate.

That's a completely different question, your claim was about parallelism.

Comment #48871113
Uh, is it resistant to parallelization across multiple sites? Because that's the situation for the scrapers. They're not trying to solve a single PoW challenge across many cores.

It's behind a flag, if you want to play with it. (The easiest way is usually just to test in Canary.)

Comment #48661675
Did you actually test? I did it and it worked fine (and zooming in confirmed that the RGB bars are nicely preserved). Be sure to put your subsampling at 4:4:4.

Why do you think it wouldn't work for a JPEG? I just made one like that, and it worked just fine.

Just remove the A record, and nearly all the scrapers disappear. :-) (And then you get one email per month or so that “your host does not resolve in DNS”.)
